介绍了斜方晶系 TmMnO 和 LuMnO 的共振软 X 射线粉末衍射实验。在 Tman 和 Mnedges 附近进行了实验，分别研究 Tm 和 Mn 磁矩。这些实验表明，对于具有E型有序基态的重稀土钙钛矿，Tm磁矩有序已经处于非铁电不相称磁相。此外，两种化合物在低温下都发现与共线 E 型锰磁结构的偏差。这些实验展示了共振软 X 射线衍射的力量，扩展到多晶 4 材料。
Resonant soft x-ray powder diffraction experiments on orthorhombic TmMnOand LuMnOare presented. Experiments were performed in the vicinity of the Tmand the Mnedges to study the Tm and Mn magnetic moments, respectively. These experiments show that for the heavy rare-earth perovskite with an E-type ordered ground state, the Tm magnetic moments order already in the nonferroelectric incommensurate magnetic phase. Additionally, deviations from the collinear E-type Mn magnetic structure at low temperatures are found for both compounds. These experiments show the power of resonant soft x-ray diffraction, extended to polycrystalline 4materials.
